Abstract
Paper industry is one industry in Indonesia which has a bright prospect in the future and contribute to the economy of Indonesia. Availability of water hyacinth not yet widely used,the planned establishment of paper mill with raw material water hyacinth. This paper mill worked by process of Acetocell. Based on the supply of raw materials, the availability of water, and the easy of transportation, so the location of establishment of the factory selected in the area of North Sulawesi.
There are 3 steps in water hyacinth paper making with the acetocell process. The first step is the pre treatment with the purpose to eliminate the impurities on raw materials. The second step is cooking and bleaching, cooking with 50% CH3COOH solution by cooking temperature 90ºC. Bleaching using 1% hydrogen peroxide and 1% sodium dithionite, from the process of bleaching obtained brightness 77%. The last stage, as well as finishing the drying stage where the pulp is reduced up to 5% water content and formed sheet.
Paper mill works and operates continuously for 300 day/year with a production capacity of 100.000 ton/year. Water hyacinth that needed is around 1899182,028 kg/day with supporting materials like CH3COOH, H2O2 and Na2S2O4. The utility needs are water sanitation, water process and make up water 25152,33421 m3/day. Waste produced from this industry is black liquor, pulp slurry leaching waste and solid waste.
Key Word: Paper, Pulp, Water hyacinth, Acetocell, Acetic Acid, Hydrogen Peroxide, Sodium Dithionite
============== Industri kertas merupakan salah satu industri di Indonesia yang memiliki prospek yang cerah di masa mendatang serta dapt memberikan kontribusi dalam perekonomian Indonesia. Ketersediaan Eceng gondok belum banyak dimanfaatkan, maka direncanakan pendirian pabrik kertas dengan bahan baku Eceng gondok. Pabrik kertas ini bekerja dengan proses acetocell. Berdasarkan ketersediaan bahan baku, kemudahan transportasi dan sumber air, rencana lokasi pendirian pabrik adalah di daerah Sulawesi Utara.
Pembuatan kertas dari Eceng gondok dibuat dengan proses acetocell melalui 3 tahap. Tahap pertama yaitu pre-treatment yang bertujuan untuk menghilangkan impurities. Tahap kedua yaitu pemasakan dan bleaching, pemasakan dengan larutan CH3COOH 50% pada temperatur 90ºC. Bleaching yang bertujuan untuk mencerahkan warna bubur pulp dengan 2 proses yaitu bleching menggunakan hidrogen peroksida 1% dan bleaching menggunakan sodium dithionite 1 % dari proses bleaching didapatkan kecerahan 77%. Tahap terakhir yaitu post-treatment yang bertujuan untuk mengurangi kadar air dalam pulp hingga 5% dan pembentukan lembaran kertas.
Pabrik kertas bekerja secara kontinyu dan beroperasi selama 300 hari/tahun dengan kapasitas produksi sebesar 100.000 ton/tahun. Eceng gondok yang dibutuhkan sebesar 1899182,028 kg/hari dengan bahan baku pendukung CH3COOH, H2O2 dan Na2S2O4. Kebutuhan utilitasnya adalah air sanitasi, air proses dan air make up yaitu 25152,33421 m3/hari. Limbah yang dihasilkan dari industri ini yaitu black liquor, limbah pencucian bubur pulp dan limbah padat.
Kata Kunci: Kertas, Pulp, Eceng gondok, Asam Asetat, Hidrogen Peroksida, Sodium Dithionite
